1. A curable corrosion-inhibiting coating composition comprising:
- a fluorinated binder; and
an effective amount of a corrosion-inhibiting compound selected from the group consisting of one or more of a corrosion-inhibiting extender, a corrosion-inhibiting rare earth compound, and a corrosion-inhibiting carbon pigment, and combinations thereof.

Abstract
Corrosion-inhibiting coating compositions which are self-priming topcoats having improved weatherability and durability are provided. The compositions contain fluorinated resins (binders), incorporate one or more corrosion-inhibiting compounds including corrosion-inhibiting extenders (a metal cation from Group I A or II A of the periodic table of the elements and an oxyanion counterion), corrosion-inhibiting rare earth compounds, and corrosion-inhibiting carbon pigments. Methods for applying the corrosion-inhibiting compositions to a substrate are also provided.
